I agree 100%. She also will thrash around violently but, they always say she is just "happy". She is going to end up hurting someone with that "happy" bullshit behavior. She reminds me of a wild animal when she is eating bc, she gets all aggressive and gets her face so close to her plate and just shovels it in her mouth as quickly as possible and when she gets done with hers, she will start trying to grab everyone else's food around her. I don't see how anyone can stand to be around her, especially when they are trying to eat. If they aren't going to fix the behavior, then they need to feed her separately from anyone else. It's just like when you have to separate pets when they eat to keep them from fighting and getting in each other's food. I know that sounds horrible but, it's the truth.
That very well could be it. They are just strange birds, I tell ya.
